Longitudinal dm) and horizontal fibers (nui) alternate throughout the capsule. Inset shows thick and thin filaments consistent with the si/e and appearance of myosin and actin. Neural axons (nv) are intermingled with muscle cells. The capsule is separated from the connective tissue of the arm (ct)by a third layer of cells (' I. which is associated with extrinsic muscle cells (cm), bv. lumen ot a blood vessel; nu. nucleus. Scale bars = 1 shape of the primary web precludes any flow-through feed- ing current. Therefore, the prey cannot be filtered from the water column, but must somehow be attracted to the mucous web. Since many deep-sea crustaceans have well-devel- oped, sensitive eyes and are attracted to light sources (Morin ft 1475). the photophores of S. syrteiisis may provide the lure. With the exception of the twisting behavior following ballooning (observed only once), the in situ behaviors of the three specimens of S. syrtensis reported here are similar to.
